Answer 1

This one's confusing :I @johnweldon1993

Answer 2

9(-x+3) -2 solve now

Answer 3

Alrightthis one is different...instead of a number...you replace every 'x' you see in g with an 'x'

Sound like nothing right? it is nothing...you just keep g the way it is...and you plug (-x + 3) in for every 'x' you see in f

Answer 4

Ohhhh that's easy...Okay so then I would get -9x+25.

Answer 5

Very good :)
